If you're going to call yourself a "web producer", surely you could take the time to learn a little about the field in which you work? I would expect a "TV producer" to know the difference between 16:9 and 4:3 aspect ratios. A web producer who doesn't know what an iframe is, and hides behind "oh I'm not technical", is not fit for purpose. Show some professional curiosity fercrissake.
